Lukasz Jastrzebski commented on SPARK-5376:
-------------------------------------------
One comment, however if you run multiple Spark applications even tough
executor-id == slave-id, multiple executors can be started on the same host.
(And every one of them will consume 1 CPU without scheduling any tasks). This
can be painful when you want to run multiple streaming applications on Mesos in
fine grained mode, because each streaming driver's executors will consume 1
CPU...
> [Mesos] MesosExecutor should have correct resources

> executor. As is, same cores as tasks and no memories.
